Rotational molding refers to a plastic manufacturing technique that produces hollow stress-free product lines. The method relies upon high temperatures and bi axial rotation to follow up with seamless, one piece objects that have varying designs, sizes and colors. This technique is also known as rotomolding or rotocasting. Sometimes the term slush molding is used for certain liquid vinyl forms.

The function that makes this different from other plastic manufacturing procedures because no pressure is called for. It also has few contenders when it comes to the production of large size hollow items which are long-lasting and inexpensive.There is a variety of items that are developed by this process including large size water tanks, automobile materials, intricate molded medical items, leisure equipment, toys, kayaks, industrial equipment among many others.This is due to the flexibility in regards to design and shapes that the process develops

Benefits of Using Rotomolding to Manufacture Plastic Products

– Relatively low tooling costs. When compared to other plastic manufacturing processes in Fillmore UT 84631, it is a cheaper way of making plastics. This is because apart from the fact that no pressure is required, the cost of mold preparation is low.

– A wide array of design options. There is no limit to the kind of design one may want to create. The roto-molding process therefore allows for the manufacturing of products that have complex shapes for different purposes.

– Size. The process provides room for the manufacturing of products of any size, large or small. As mentioned earlier, it has few competitors when it comes to the making of large tanks at low costs.

– Low risk. Due to the low costs of creating a mould, the process allows for test runs before one can decide whether to do mass production. It therefore minimizes the risk of losing a lot of investment.

– Durable products. The process allows for even coating of the mould with the heated polymer, giving the product a wall with uniform thickness. It also gives the option of double coating for increased durability. Sometimes metal inserts are placed inside the mould to further strengthen the product.

– Environmentally friendly. There is no waste that could have a negative impact on the environment because the products that cannot be used are reground and reused as polymer.

Examples of Products Made by Rotational Molding

Rotocasting is a very versatile process, making it possible to create a variety of products for different industries.

Furniture– We have plastic cabinets, chairs and tables made from this form of moulding.

There are numerous Utah plastic products also that have been made for the marine industry, lighting, waste storage and transportation, kayaks etc.

Few Disadvantages – There are nominal disadvantages that have been associated with rotocasting. For instance:

– The process is relatively slow when compared to injection moulding.

– There is a limitation when it comes to the type of raw material you can use. Only poly based and nylon polymers can be used.

– The process comes with an increased cost because the polymer has to be ground to powder form before use. These limitations are often overlooked considering that the process is still relatively cheap and offers more in terms of variety when it comes to the finished range of products.

Remember – There are new developments and discoveries that are being made as the world of plastic manufacturing in Fillmore Utah continuously. For instance, tests are being done to see whether there are other materials that can be used for this process. But so far, rotomoulding offers a good option for the production of a wide range of inexpensive plastic products.

The Rotomoulding Method in Detail

This molding system has been used since early times for creatingvseverl items. Egyptians for instance, worked with rotational molding solutions in the manufacturing of ceramics. The Swiss were also using this rotation type to make hollow chocolate eggs. Some plastic products in the USA were manufactured using this technique some time between 1940 and 1950. The procedure has however taken long to catch on because it was considered as being a very slow-moving process

1. Mould readying. A fixed volume of polymer in powder form is filled into a hollow mould. The mould is usually made of cast aluminium or sheet steel material. The color intended for the final goods is pre compounded into the polymer. The most generally used powder resin is polythene, but polyvinyl chloride and nylon can also be used in this style of plastic production.

Pre-heating of the oven follows, and it can be done by either conduction, convection or sometimes radiation. It is heated up to temperatures between 500-700F. The mould with the powdered polymer is then locked and installed within the oven.

2. The heating up and fusion phase. Once inside the oven, the mould is rotated on two axis so the powdered polymer liquefies from the heat and layers the inside if the mold. The spinning is done gradually, about 20 revolutions per minute. Something that is crucial at this moment is the amount of time the mould will spend within the oven. If it stays to long, the material will lose stability and strength, generating a faulty product. If it is removed from the oven prematurely, the polymer will not have melted properly, which produces bubbles in the completed product line.

3. Mould cooling down. When the material has completely spent the right amount of time in the oven, it is then extracted for cooling. This can be done by air or water, or sometimes a mixture of both which generates a cool mist. When the product cools, it shrinks somewhat for ease of removal from the mould. This is an additional procedure that depends upon a lot on the right timing, since quick cooling shrinks the material too fast, causing warping of the item.

4. The removing or de-molding step. When the product inside te mold has cooled properly, the person taking care of the operation can then extract the completed product from the mold. The technique is repeated from the start, giving a series of similar items.
